Which ISP are you using? I only block ISPs that are notorious for letting spammers and abusers run free on their networks.
I must have used a crock site, just because I did not want to tick off folks who may have written to me.
LOL! Write private, if that's the only way!
I have written private. Twice. Two emails. JLO.
I won't post my ISP address anymore.
Anywhere.
